Base of Operations: A building used
by Dr. Doom, in Manhattan, New York

First Appearance: Fantastic Four I#144 (March,
1974)

Powers/Abilities: The Seeker had
superhuman strength (Class 25?) and durability. It has the equivalent of enhanced durabilty and stamina. In place of hands
it had nuclear discharger prods which released a powerful burst
of energy, released only upon contact. The "vibro-sensor" atop it's head was a tracking device, with a range of half a mile, and could detect hidden and invisible targets. It was programmed to defeat certain foes, and may or
may not have been able to fly.

History: The Seeker was built by Dr.
Doom and programmed to defeat Darkoth and the Fantastic Four.

(Fantastic Four I#144) - Darkoth and the
Fantastic Four attempted to tunnel underneath the Baxter Building
to enter it in secret so that they might escape a plot of Dr.
Doom's. Doom sent the Seeker to destroy them. The Seeker swatted
the Thing aside, shocked Mr. Fantastic, and threw off Darkoth
when he leapt atop him. However, Medusa took advantage of the
distraction to bean the Seeker in the back of the head with a
rock. The Thing then leapt back into the fray and put the kibosh
on the Seeker with a one-two combination. The Thing was
disappointed that he didn't even get a chance to say, "It's
clobberin' time!"

Darkoth and the others brought the Seeker into
the Baxter Building, where Reed hollowed it out and then wrapped
its form around Darkoth. Posing as the Seeker, Darkoth then
entered Doom's base, unnoticed by his security system programmed
only to notice the unfamiliar. Darkoth freed Doom's prisoners,
Wyatt Wingfoot and the Human Torch, before confronting Doom
himself. Doom blasted the Seeker, intending to destroy it for its
betrayal, but was surprised when Darkoth stood revealed, unharmed
by the blast that had shredded the Seeker covering.
